Migrate to GitHub actions (#878)

* Drop Travis CI
* Add Github Actions
  * Added `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` secrets to this repo
  * Rotated the saucelabs access key for good measure
  * Caching `./node_modules`
  * Utilizing `./buildtools/sauce_connect.sh` in Actions
    * the version of `sc` was depreciated, upgraded to `4.6.5`
    * if `$GITHUB_RUN_ID` is present, use that for the tunnel identifier
  *  Update `protractor.conf.js` to check for Github Actions ENV variables
